1. 21. Energy systems and urban circularity: evaluating the performance of indicators for district heating and cooling systems according to the circular economy principles

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Joana Rebola; [2022]
   Keywords : sustainable development; district heating and cooling; circular economy; indicators; assessment;

   Abstract : The circular economy model has been proposed as a possible strategy for sustainable development in urban areas, implying that its core principles need to be cascaded down to various sectors, including the energy sector. District heating and cooling systems have great potential to enhance circularity on an urban level due to the establishment of synergies between different sectors, the incorporation of renewable energy sources and high efficiency.

3. 22. Energy supply system for a high-rise building in Germany : Optimization of a heating and cooling supply system made with plant simulations

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Ida Almén; Elin Johansson; [2022]
   Keywords : energy supply system; absorption chiller; compression chiller; Germany;

   Abstract : The building sector has great potential for energy savings since it is responsible for nearly a third of the global energy use. As oil, coal and natural gas continues to hold a big share of the energy mix it is important to work towards introducing more renewable energy alternatives. READ MORE

4. 23. Data center cooling solutions : A techno-economical case study of a data center in Sweden

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Joel Sjökvist; Fredrik Magnusson; [2022]
   Keywords : Energy systems; Data center cooling; Free cooling; Air cooling; Geothermal cooling; Mechanical cooling; District cooling; Building conversion; Dry cooler; Cooling machine; Borehole; PUE;

   Abstract : Given the coinciding growth-trend in the production of consumer electronics and generation of data, the increase in server halls and data centers, as a means for hosting storage capacity for the generated data, has been prominent over the last decades. The establishment of data centers in already existing infrastructure can entail major changes in terms of energy system design. READ MORE

5. 24. 5th Generation District Heating and Cooling : A High-Level Simulation Model of a Novel District Energy Network

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Viktor Olofsson; [2022]
   Keywords : 5GDHC; district heating; district cooling; district energy; energy systems; renewable energy;

   Abstract : 5th generation district heating and cooling is a novel approach to district heating and cooling networks. Instead of a centralized energy supply, the technology relies on multiple building-level energy centers, equipped with heat pumps and chillers. READ MORE

6. 25. Comparison of a whole-building and HVAC-system simulation model with measured data from a new office building

   University essay from KTH/Byggvetenskap

   Author : Diana Radamson; [2022]
   Keywords : Office building; HVAC-system; indoor air temperature; simulation model; IDA ICE.;

   Abstract : Energy calculations are used for many purposes, for example during the design andconstruction phase to comply with Boverket’s building regulations, energy declarations or toachieve energy saving in a building. A main problem in the design process of a new building,is to accurately predict the energy performance. READ MORE
